HINGE.

Application filed May 31, 1922. SerialV No. 564,846.

To all whom t may concern.'

Be it known that I, BURT M. Moons, Aa citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain' nev,7 and useful Improvements in Hinges, of Which the following is a specification.

It is the object of my invention to provide a simple door or gate hinge of few parts easily formed and assembled and provided With an easily replaceable resilient means for normally holding the hinge in a closed position.

In the drawing Figure l is an outside elevation of my improved hinge.

Figure 2 is an inside elevation of the same.

Figure 3 is a sectional view on 3 3 of Figure l.

Figure l is a plan view of blank for one portion of the hinge after cutting but before shaping. l

Referring more particularly to the drawing, 1 indicates one leaf of the hinge attachable to a door casing and having one edge turned outwardly at substantially right anglee thereto as at 2 and thence turned back- Wardly upon itself and cut out as at 3a to form loops 3 and a plate il. Plate l is continued past the plane of leaf l as shown whereby it may be secured to the edge of a door casing as 5. rihe inner edge of plate 4- is extended in part to form an ear 6 having an orifice 7 therein.

The second leaf of the hinge is shown at 8 and is attachable to the side of the door reverse to theV side of the casing to which leaf l is attached and is provided With an ear 9 provided with an orifice l0. Leaf 8 is bent outwardly at substantially right angles to form plate 1l Which is provided With terminal loops 12, alternating With loops 3, the loops l2 and 3 being in alignment and engaging a pin 13.

At 14 is shown a coiled spring attached to ears 6 and 9 through orifices 7 and 10 Whereby to normally hold plates 4 and 11 in parallel relation to each othery and thence to hold door 15 in closed position With relation to frame 16.

When the hinge is constructed as described and mounted upon a door and casing as indicated, the opening of the door 15 causes the spring 14 to assume a position such as shown in dotted lines at 17. To prevent interference with the action of spring 14 and also to prevent undue Wear upon either the spring or hinge corner, a recess 18 is formed in the corner of leaf 8 at the point where the spring contacts upon opening the door.

It may now readily be seen that the hinge herein disclosed is easily made'and of few parts since there are but four pieces namely, the two leaves, the spring and the pin. The construction of the hinge is such that the cutting and bending of each leaf is a simple operation as also is the assembling of the leaves, pin and spring.

The spring is so arranged that its action is positive and powerful, yet can be removed and replaced in a moments time. Since no special design is required an old spring may be readily replaced at little cost and With little delay. n

The formation of the recess 18 is iniportant inasmuch as it renders .the device practical with but small projections or ears on the leaves.

It is to be understood, of course, that While l have herein shown and described the particular embodiment of my invention desired, that changes in form, proportion, construction and method of operation may be made Within the scope of the appended claim.

It is to be further understood that l do not Wish to confine myself to a form of hinge in which the spring i4 is used as the hinge Without the spring may be useful in many applications.

I claim A hinge comprising an element having tivo leaves arranged at right angles to each other for attachment to a door casing, one of said leaves having an ear extending out- Wardly therefrom, and a second element having leaves arranged at right angles to each other for attachment to a door, one of said leaves having an ear extending outwardly therefrom, a spring Vconnecting said first and said last mentioned ears, and means for pivotally connecting said elements at a point remote from said ear I said ears being arranged to normally maintain said spring in parallel relation to the door and frame upon which it is mounted, but engaging one element When the door is opened.
